    Structure of the VHL-ElonginC-ElonginB complex: implications for VHL tumor suppressor function (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-04-16
    Description: Mutation of the VHL tumor suppressor is associated with the inherited von Hippel-Lindau (VHL) cancer syndrome and the majority of kidney cancers. VHL binds the ElonginC-ElonginB complex and regulates levels of hypoxia-inducible proteins. The structure of the ternary complex at 2.7 angstrom resolution shows two interfaces, one between VHL and ElonginC and another between ElonginC and ElonginB. Tumorigenic mutations frequently occur in a 35-residue domain of VHL responsible for ElonginC binding. A mutational patch on a separate domain of VHL indicates a second macromolecular binding site. The structure extends the similarities to the SCF (Skp1-Cul1-F-box protein) complex that targets proteins for degradation, supporting the hypothesis that VHL may function in an analogous pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stebbins, C E -- Kaelin, W G Jr -- Pavletich, N P -- New York, N.Y. -- Science. 1999 Apr 16;284(5413):455-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Structural Biology, Joan and Sanford I.

    Three-dimensional structures of the ligand-binding domain of the bacterial aspartate receptor with and without a ligand (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-12-09
    Description: The three-dimensional structure of an active, disulfide cross-linked dimer of the ligand-binding domain of the Salmonella typhimurium aspartate receptor and that of an aspartate complex have been determined by x-ray crystallographic methods at 2.4 and 2.0 angstrom (A) resolution, respectively. A single subunit is a four-alpha-helix bundle with two long amino-terminal and carboxyl-terminal helices and two shorter helices that form a cylinder 20 A in diameter and more than 70 A long. The two subunits in the disulfide-bonded dimer are related by a crystallographic twofold axis in the apo structure, but by a noncrystallographic twofold axis in the aspartate complex structure. The latter structure reveals that the ligand binding site is located more than 60 A from the presumed membrane surface and is at the interface of the two subunits. Aspartate binds between two alpha helices from one subunit and one alpha helix from the other in a highly charged pocket formed by three arginines. The comparison of the apo and aspartate complex structures shows only small structural changes in the individual subunits, except for one loop region that is disordered, but the subunits appear to change orientation relative to each other. The structures of the two forms of this protein provide a step toward understanding the mechanisms of transmembrane signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Milburn, M V -- Prive, G G -- Milligan, D L -- Scott, W G -- Yeh, J -- Jancarik, J -- Koshland, D E Jr -- Kim, S H -- AI 30725/AI/NIAID NIH HHS/ -- DK09765/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1991 Nov 29;254(5036):1342-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1660187" target="_blank"〉PubMed〈/a〉

    Inclusion of thermal motion in crystallographic structures by restrained molecular dynamics (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-09-07
    Description: A protein crystal structure is usually described by one single structure, which largely omits the dynamical behavior of the molecule. A molecular dynamics method with a time-averaged crystallographic restraint was used to overcome this limitation. This method yields an ensemble of structures in which all possible thermal motions are allowed, that is, in additional to isotropic distributions, anisotropic and anharmonic positional distributions occur as well. In the case of bovine pancreatic phospholipase A2, this description markedly improves agreement with the observed x-ray diffraction data compared to the results of the classical one-model structure description. Time-averaged crystallographically restrained molecular dynamics reveals large mobilities in the loops involved in lipid bilayer association.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gros, P -- van Gunsteren, W F -- Hol, W G -- New York, N.Y. -- Science. 1990 Sep 7;249(4973):1149-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉BIOSON Research Institute, University of Groningen, The Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2396108" target="_blank"〉PubMed〈/a〉

    Structural basis for the activation of cholera toxin by human ARF6-GTP (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-08-16
    Description: The Vibrio cholerae bacterium causes devastating diarrhea when it infects the human intestine. The key event is adenosine diphosphate (ADP)-ribosylation of the human signaling protein GSalpha, catalyzed by the cholera toxin A1 subunit (CTA1). This reaction is allosterically activated by human ADP-ribosylation factors (ARFs), a family of essential and ubiquitous G proteins. Crystal structures of a CTA1:ARF6-GTP (guanosine triphosphate) complex reveal that binding of the human activator elicits dramatic changes in CTA1 loop regions that allow nicotinamide adenine dinucleotide (NAD+) to bind to the active site. The extensive toxin:ARF-GTP interface surface mimics ARF-GTP recognition of normal cellular protein partners, which suggests that the toxin has evolved to exploit promiscuous binding properties of ARFs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Neal, Claire J -- Jobling, Michael G -- Holmes, Randall K -- Hol, Wim G J -- AI-31940/AI/NIAID NIH HHS/ -- AI-34501/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2005 Aug 12;309(5737):1093-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16099990" target="_blank"〉PubMed〈/a〉

    Structure of an HIF-1alpha -pVHL complex: hydroxyproline recognition in signaling (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-05-11
    Description: The ubiquitination of the hypoxia-inducible factor (HIF) by the von Hippel-Lindau tumor suppressor (pVHL) plays a central role in the cellular response to changes in oxygen availability. pVHL binds to HIF only when a conserved proline in HIF is hydroxylated, a modification that is oxygen-dependent. The 1.85 angstrom structure of a 20-residue HIF-1alpha peptide-pVHL-ElonginB-ElonginC complex shows that HIF-1alpha binds to pVHL in an extended beta strand-like conformation. The hydroxyproline inserts into a gap in the pVHL hydrophobic core, at a site that is a hotspot for tumorigenic mutations, with its 4-hydroxyl group recognized by buried serine and histidine residues. Although the beta sheet-like interactions contribute to the stability of the complex, the hydroxyproline contacts are central to the strict specificity characteristic of signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Min, Jung-Hyun -- Yang, Haifeng -- Ivan, Mircea -- Gertler, Frank -- Kaelin, William G Jr -- Pavletich, Nikola P -- New York, N.Y. -- Science. 2002 Jun 7;296(5574):1886-9.

    Structure of the vesicular stomatitis virus nucleoprotein-RNA complex (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-06-17
    Description: Vesicular stomatitis virus is a negative-stranded RNA virus. Its nucleoprotein (N) binds the viral genomic RNA and is involved in multiple functions including transcription, replication, and assembly. We have determined a 2.9 angstrom structure of a complex containing 10 molecules of the N protein and 90 bases of RNA. The RNA is tightly sequestered in a cavity at the interface between two lobes of the N protein. This serves to protect the RNA in the absence of polynucleotide synthesis. For the RNA to be accessed, some conformational change in the N protein should be necessary.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Green, Todd J -- Zhang, Xin -- Wertz, Gail W -- Luo, Ming -- AI050066/AI/NIAID NIH HHS/ -- R37 AI012464/AI/NIAID NIH HHS/ -- R37 AI012464-28/AI/NIAID NIH HHS/ -- R37 AI012464-29/AI/NIAID NIH HHS/ -- R37 AI012464-30/AI/NIAID NIH HHS/ -- R37 AI012464-31/AI/NIAID NIH HHS/ -- R37AI012464/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2006 Jul 21;313(5785):357-60.

    A Burkholderia pseudomallei toxin inhibits helicase activity of translation factor eIF4A (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-11-15
    Description: The structure of BPSL1549, a protein of unknown function from Burkholderia pseudomallei, reveals a similarity to Escherichia coli cytotoxic necrotizing factor 1. We found that BPSL1549 acted as a potent cytotoxin against eukaryotic cells and was lethal when administered to mice. Expression levels of bpsl1549 correlate with conditions expected to promote or suppress pathogenicity. BPSL1549 promotes deamidation of glutamine-339 of the translation initiation factor eIF4A, abolishing its helicase activity and inhibiting translation. We propose to name BPSL1549 Burkholderia lethal factor 1.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3364511/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3364511/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cruz-Migoni, Abimael -- Hautbergue, Guillaume M -- Artymiuk, Peter J -- Baker, Patrick J -- Bokori-Brown, Monika -- Chang, Chung-Te -- Dickman, Mark J -- Essex-Lopresti, Angela -- Harding, Sarah V -- Mahadi, Nor Muhammad -- Marshall, Laura E -- Mobbs, George W -- Mohamed, Rahmah -- Nathan, Sheila -- Ngugi, Sarah A -- Ong, Catherine -- Ooi, Wen Fong -- Partridge, Lynda J -- Phillips, Helen L -- Raih, M Firdaus -- Ruzheinikov, Sergei -- Sarkar-Tyson, Mitali -- Sedelnikova, Svetlana E -- Smither, Sophie J -- Tan, Patrick -- Titball, Richard W -- Wilson, Stuart A -- Rice, David W -- 085162/Wellcome Trust/United Kingdom -- BB/D011795/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/D524975/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E025293/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- WT085162AIA/Wellcome Trust/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2011 Nov 11;334(6057):821-4. doi: 10.1126/science.1211915.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and Biotechnology, Krebs Institute, University of Sheffield, Sheffield S10 2TN, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22076380" target="_blank"〉PubMed〈/a〉

    Crystal structure of a lipid G protein-coupled receptor (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-02-22
    Description: The lyso-phospholipid sphingosine 1-phosphate modulates lymphocyte trafficking, endothelial development and integrity, heart rate, and vascular tone and maturation by activating G protein-coupled sphingosine 1-phosphate receptors. Here, we present the crystal structure of the sphingosine 1-phosphate receptor 1 fused to T4-lysozyme (S1P(1)-T4L) in complex with an antagonist sphingolipid mimic. Extracellular access to the binding pocket is occluded by the amino terminus and extracellular loops of the receptor. Access is gained by ligands entering laterally between helices I and VII within the transmembrane region of the receptor. This structure, along with mutagenesis, agonist structure-activity relationship data, and modeling, provides a detailed view of the molecular recognition and requirement for hydrophobic volume that activates S1P(1), resulting in the modulation of immune and stromal cell responses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3338336/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3338336/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hanson, Michael A -- Roth, Christopher B -- Jo, Euijung -- Griffith, Mark T -- Scott, Fiona L -- Reinhart, Greg -- Desale, Hans -- Clemons, Bryan -- Cahalan, Stuart M -- Schuerer, Stephan C -- Sanna, M Germana -- Han, Gye Won -- Kuhn, Peter -- Rosen, Hugh -- Stevens, Raymond C -- AI055509/AI/NIAID NIH HHS/ -- AI074564/AI/NIAID NIH HHS/ -- P50 GM073197/GM/NIGMS NIH HHS/ -- P50 GM073197-08/GM/NIGMS NIH HHS/ -- R01 AI055509/AI/NIAID NIH HHS/ -- R01 AI055509-04/AI/NIAID NIH HHS/ -- U01 AI074564/AI/NIAID NIH HHS/ -- U01 AI074564-04/AI/NIAID NIH HHS/ -- U54 GM094618/GM/NIGMS NIH HHS/ -- U54 GM094618-02/GM/NIGMS NIH HHS/ -- U54 MH084512/MH/NIMH NIH HHS/ -- U54 MH084512-04/MH/NIMH NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Feb 17;335(6070):851-5. doi: 10.1126/science.1215904.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Receptos, 10835 Road to the Cure, San Diego, CA 92121, USA. mhanson@receptos.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22344443" target="_blank"〉PubMed〈/a〉

    Structural basis for molecular recognition at serotonin receptors (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-03-23
    Description: Serotonin or 5-hydroxytryptamine (5-HT) regulates a wide spectrum of human physiology through the 5-HT receptor family. We report the crystal structures of the human 5-HT1B G protein-coupled receptor bound to the agonist antimigraine medications ergotamine and dihydroergotamine. The structures reveal similar binding modes for these ligands, which occupy the orthosteric pocket and an extended binding pocket close to the extracellular loops. The orthosteric pocket is formed by residues conserved in the 5-HT receptor family, clarifying the family-wide agonist activity of 5-HT. Compared with the structure of the 5-HT2B receptor, the 5-HT1B receptor displays a 3 angstrom outward shift at the extracellular end of helix V, resulting in a more open extended pocket that explains subtype selectivity. Together with docking and mutagenesis studies, these structures provide a comprehensive structural basis for understanding receptor-ligand interactions and designing subtype-selective serotonergic drugs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3644373/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3644373/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Chong -- Jiang, Yi -- Ma, Jinming -- Wu, Huixian -- Wacker, Daniel -- Katritch, Vsevolod -- Han, Gye Won -- Liu, Wei -- Huang, Xi-Ping -- Vardy, Eyal -- McCorvy, John D -- Gao, Xiang -- Zhou, X Edward -- Melcher, Karsten -- Zhang, Chenghai -- Bai, Fang -- Yang, Huaiyu -- Yang, Linlin -- Jiang, Hualiang -- Roth, Bryan L -- Cherezov, Vadim -- Stevens, Raymond C -- Xu, H Eric -- P50 GM073197/GM/NIGMS NIH HHS/ -- R01 DA027170/DA/NIDA NIH HHS/ -- R01 DA27170/DA/NIDA NIH HHS/ -- R01 DK071662/DK/NIDDK NIH HHS/ -- R01 MH061887/MH/NIMH NIH HHS/ -- R01 MH61887/MH/NIMH NIH HHS/ -- U19 MH082441/MH/NIMH NIH HHS/ -- U19 MH82441/MH/NIMH NIH HHS/ -- U54 GM094618/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 May 3;340(6132):610-4. doi: 10.1126/science.1232807.
